The key aim of the study is to define the two biologically and clinically distinct entities: progressive versus stable myeloma precursor conditions.
Diagnosis of MGUS and SMM will be made in accordance with the clinical diagnostic criteria set forth by the 2014 International Myeloma Working Group (IMWG) Revised Criteria.2
The diagnoses will be confirmed by either serum/urine protein electrophoresis, immunofixation and light-chain assays; or immunohistochemistry analyses of the bone marrow biopsy, or a combination of these tests.
Age greater than or equal to 18 years.
Eastern Cooperative Oncology Group (ECOG) performance status of 0-3.
A diagnosis of MM as defined as any patient with detectable M-protein in blood and/or urine, monoclonal plasma cells in the bone marrow, and evidence of end-organ damage based on the Calcium Elevation, Renal Failure, Anemia, and Bone Disease (CRAB) criteria and/or myeloma-defining events.
Patients who have received previous therapy for MM.
Patients with known plasma cell or related lymphoid (e.g. lymphoplasmacytic lymphoma, Amyloid Light chain (AL) amyloidosis)
Confirmation of pathological diagnosis is required either from the initial pathology review report or review from the UM/SCCC Hematopathologist in accordance with the clinical diagnostic criteria set forth by the International Myeloma Working Group (IMWG) or World Health Organization (WHO). Tumor tissue that has been previously collected and is available for study or that can be collected with minimal additional risk to the patient during sampling required for routine patient care or required testing on a University of Miami (UM) /Sylvester Comprehensive Cancer Center (SCCC) research protocol will be used for diagnosis.
Adult participants diagnosed with MGUS or SMM.
